常見例句雙語例句This paper presents the field estimation on rock mass quality by means of vibrational decrement.本文介紹了一種在現(xiàn)場用振動(dòng)衰減系數(shù)來估計(jì)巖體質(zhì)量的新方法。118.145.16.223Therefore it is considered that the decrement of gravity vertical gradient is caused by mountain mass distribution.分析了佘山重力垂直梯度偏小的原因,認(rèn)為這是由于山體質(zhì)量分布引起的。The decrement of higher modal response of the rotor system is lost when damper mass-factor exceeds a limiting range.當(dāng)質(zhì)量參數(shù)超出某有效區(qū)間時(shí),系統(tǒng)將失去對高階模態(tài)響應(yīng)的衰減作用。 返回 mass decrement
